It was almost dark, indeed most of the arc over which his eyes could travel was perfectly so. But here and there he noticed parallelograms of a less inky blackness, and after some time the significance of these penetrated his brain and he knew where he was.

He was lying on his back on the ground in the half-built house from which he had taken the ladder, and the parallelograms were the openings in the walls into which doors and windows would afterwards be fitted. Against the faint light without, which he took to be that of the moonlit sky, he could see dimly the open joists of the floor above him, a piece of the herringbone strutting of which cut across the space for one of the upstairs windows.

Feeling slightly better he tried his pocket, to find, as he expected, that the tracing was gone. Presently he attempted some more extensive movement. But at once an intolerable pang shot through him, and, sick and faint, he lay still. With a dawning horror he wondered whether his back might not be broken, or whether the blow on his head might not have produced paralysis. He groaned aloud and sank back once more into unconsciousness.

After a time he became sentient again, sick and giddy, but more fully conscious. While he could not think collectedly, the idea became gradually fixed in his mind that he must somehow get away from his present position, partly lest his enemies might return to complete their work, and partly lest, if he stayed, he might die before the workmen came in the morning. Therefore, setting his teeth, he made a supreme effort and, in spite of the terrible pain in his head, succeeded in turning over on to his hands and knees.

In this new position he remained motionless for some time, but presently he began to crawl slowly and painfully out towards the road. At intervals he had to stop to recover himself, but at length after superhuman efforts he succeeded in reaching the paling separating the lot from Hopefield Avenue. There he sank down exhausted and for some time lay motionless in a state of coma.

Suddenly he became conscious of the sound of light but rapid footsteps approaching on the footpath at the other side of the paling, and once more summoning all his resolution he nerved himself to listen. The steps drew nearer until he judged their owner was just passing and then he cried as loudly as he could: “Help!”

The footsteps stopped and Cheyne gasped out: “Help! I’ve hurt my head: an accident.”

There was a moment’s silence and then a girl’s voice sounded.

“Where are you?”

“Here,” Cheyne answered, “at the back of the fence.” He felt dimly that he ought to give some explanation of his predicament, and went on in weak tones: “I was looking through the house and fell. Can you help me?”
